lhe it known that l, Von Miiu'riN, u citizen of the United States, residing at Abiin the eounly of Taylor and State of :e have invented certain new and useful Ilnu'iroveznents gprin r il lieels, of which the :l olloW-ing is a specification.

This iinrention relates to vehicle- Wheels and more particularly to that class of wheels in which spring-spokes are utilized to pro- \i le resilience therein for utility in line of the usual vehicle-springs; and the invenlion eonsisl's in features of novelty hereinafter l'ully (leseriheil, and pointed out in the eluiins.

o designates flat spring-spokes the widened inner enrls 'Z of which are slightly curved {seel i l and Ti) us at 8. The outer encls of the springs terminate in u ilmvnuurrlly projecting prong 9 and a short lirtuu-ce from the prong 9 are :1 pair of open i'urerl ears l0. .ln Fig. (3 l' have illustrated a ?Il()(llllQ{l form of spoke in Whieh it wi l he "1 tha the spokes are nuule in pairs iu 'rall'g Connected at their inner ends by the ourrerl. u'el) ll.

Patented Aug 5, 1913. Serial No. 605,978.

The inner ends of the spokes are secured within the slots l and the curved extremities thereof lie within and conform to the Walls of the bore 3. A boxing 1% has a cup '15 on one end adapted to engage the outer sicle edges 01: the spokes, and an annular ex lending flange forming a securing means for the spokes and preventany longitudinal and vertical movement of the above mentioned spokes, and a hollow spindle 16 adopted to extend through the bore 3 to form a hearing for one end of an axle (not shown). The spindle is externally screW- threaded nt 17 to engage threaded inner end of the bor 3.

As hereinheforo stated the outer ends of the spokes are provided with a prong 9 and a pair of :ipertured ears 10, the former being adapted to he forced into the inner, or im portion of the tread member 13, and the latter adopted to engage between the rings l2 and the tread portion. Pins 18 passing lransvorsely through the rings 12 apertureol ou s l0 and trave portion 13 securely conthese parts together.

z'oni the foregoing it will be seen that the spokes (l are securely elan'ipetl Wllllil] the hub 1 and at the same time are readily interel langeahle.

To (lelaeh av spoke, or pair of spokes, (aooordingto .Whieh form is used) it merely necessary to unscrew the cap 1.5, and remove the pins 18, whereupon the spokes may he Withdrawn from the slot- 4. 1

Having thus described my invention, What eloim is:

A wheel comprising a huh, said huh having an annular llauge forming a securing means for the spokes, sairl spokes having their inner enils eurvoil to correspond with u curvature of the hub, the outer ends provi le l 'wil'h outwardly extending tongues and outwardly ()Xllllfillllfl flanges forming hastening menus for securing the spokes to the rim.
